Issue #332 Resolved

Summary: This pull request resolves issue #332 by adding implementations for the following data structures to the repository:

1. Array

• Insert an element at a specified location.
• Access/Search for an element.
• Delete an element from a specified location.

2. Queue

• Add (enqueue) an element.
• Peek at the front element.
• Remove (dequeue) an element.

Implementation Details:

Array: The array operations enable insertion, search, and deletion functionalities at specified indices, providing a clear demonstration of fundamental array manipulation techniques.
Queue: The queue implementation includes standard enqueue, peek, and dequeue methods, simulating a basic First-In-First-Out (FIFO) data structure.
